Abstract
kde R je metyl alebo etyl. Příprava týchto solí sa može prevádza! posobením 2-aminobenzoovej kyseliny na 3-/2-aminoetyl/ aminopropyl-třimetoxysilan alebo 3-/2-aminoetyl/aminopropyltrietoxysilem v prostředí vo vodě rozpustného alkoholu pri teplote 0 až 40° C. Silany sú účinné ako prostriedky na zvýšenie pevnosti v lahu skleněných vlákien.where R is methyl or ethyl. The preparation of these salts can be carried out by reacting 2-aminobenzoic acid with 3-(2-aminoethyl)aminopropyltrimethoxysilane or 3-(2-aminoethyl)aminopropyltriethoxysilane in a water-soluble alcohol medium at a temperature of 0 to 40° C. Silanes are effective as agents for increasing the strength of glass fibers in the bottle.
Description
Predmetom vynálezu sú nové organokremioité amóniové soli kyseliny aminobenzoovej. Organokremičité zlúčeniny, hlavně rožne substituované trialkoxysilany našli široké uplatnenie k úpravě skleněných vlákien- Z dovodu, že povnosí v íahu skleněných vlákien vplýva na celý rad technologických ope iií sú híadané rožne zlúčeniny, ktoré zvyšujú ich pevnosí. Zistili sme, že je možné zvýšií ich pevnost pri použití zlúčenín podía vynálezu·.The present invention provides novel organosilicon ammonium salts of aminobenzoic acid. Organosilicon compounds, especially the various substituted trialkoxysilanes, have found wide application in the treatment of glass fibers. We have found that it is possible to increase their strength by using the compounds of the invention.
Vynález popisuje nové organokremioité amóniové soli kyseliny aminobenzoovej obecného vzorcaThe present invention provides novel organo-silicon ammonium salts of the aminobenzoic acid of the general formula
kde R je metyl alebo etyl.wherein R is methyl or ethyl.
Příprava týchto solí sa može uskutečňovat posobením- 2-aminobenzoovej kyseliny na 3-/2aminoětyl/aminopropyltrimetoxysilan alebo 3-/2-aminoetyl/aminopropyltrietoxysilan v prostředí vo vodě rozpustného alkoholu pri teplote 0 až 40° 0.The preparation of these salts can be carried out by coupling 2-aminobenzoic acid to 3- (2-aminoethyl) aminopropyltrimethoxysilane or 3- (2-aminoethyl) aminopropyltriethoxysilane in a water-soluble alcohol at 0 to 40 ° 0.
Zistili sme, že alkoxyskupina nemá' vplyv na účinnosí týchto zlúčenín ako prostriedkov na zvýšenie pevnosti v íahu vlákien·We have found that the alkoxy group does not affect the activity of these compounds as a fiber tensile strength enhancer.
Vynález je áalej objasněný formou príkladov.The invention is further illustrated by way of examples.

Příprava sa prevádzala v banke opatrenej miešadlom, teplomerom a oddělovacím lievikom·The preparation was carried out in a flask equipped with a stirrer, a thermometer and a separatory funnel.

Do banky sa předložila kyselina a alkohol. Za miešania sa'pomaly přidával silan tak, aby teplota neprestúpila 30°C /cca 40 min./. Kvartenizáoia je kvantitativná a soí je prakticky neobmedzene rozpustná vo vodě* Rozpuštěním sílánu vo vodě sa připravil roztok obsahujúoi 0,2 % soli vo vodě. Tento sa použil k úpravě koronizovanej sklenenej tkaniny z E-skla o s plátnovou vazbou o hmotnosti 200 g/m , k výrobě ktorej bolo použité vlákno o priemere 9/um. Tkanina sa upravila ponořením do roztoků· silanu na 5 minút. Po cca 8 h predsušenia sa fixovala pri 105° C 1 hodinu. Rovnakým spósobom sa vyhodnotil aj základný aminosilan. Dosiahnuté výsledky sú uvedené v tabuíke.The flask was charged with acid and alcohol. The silane was added slowly with stirring so that the temperature did not rise above 30 ° C (ca. 40 min.). The quaternization is quantitative and the salt is practically limitlessly soluble in water. By dissolving the silane in water a solution containing 0.2% salt in water is prepared. This was used to treat coronized E-glass corrugated glass cloth with a linen weave weight of 200 g / m 2 using a 9 µm diameter fiber. The fabric was treated by immersion in silane solutions for 5 minutes. After about 8 hours of pre-drying, it was fixed at 105 ° C for 1 hour. The basic aminosilane was evaluated in the same way. The results obtained are shown in the table.
